2468253c9a Define EIGEN_CPLUSPLUS and replace most __cplusplus checks. 
The macro `__cplusplus` is not defined correctly in MSVC unless building
with the the `/Zc:__cplusplus` flag. Instead, it defines `_MSVC_LANG` to the
specified c++ standard version number.

Here we introduce `EIGEN_CPLUSPLUS` which will contain the c++ version
number both for MSVC and otherwise.  This simplifies checks for supported
features.

Also replaced most instances of standard version checking via `__cplusplus`
with the existing `EIGEN_COMP_CXXVER` macro for better clarity.

Fixes: #2170

68f69414f7 Workaround for doxygen class template titles in which the template 
part of the class signature is lost due to a problem with forward
declarations.  The problem is probably caused by doxygen bug #7689.
It is confirmed to be fixed in doxygen >= 1.8.19.

280f4f2407 Enable MathJax in Doxygen.in 
Note that HTTPS must be used against the MathJax CDN when hosted on `eigen.tuxfamily.org` (which uses HTTPS) in order to avoid `Mixed Content`-errors from browsers. Using HTTPS for MathJax also works if the Eigen docs are hosted on plain HTTP.

5c4e19fbe7 Possibility to specify user-defined default cache sizes for GEBP kernel 
Some architectures have no convinient way to determine cache sizes at
runtime. Eigen's GEBP kernel falls back to default cache values in this
case which might not be correct in all situations.

This patch introduces three preprocessor directives

  `EIGEN_DEFAULT_L1_CACHE_SIZE`
  `EIGEN_DEFAULT_L2_CACHE_SIZE`
  `EIGEN_DEFAULT_L3_CACHE_SIZE`

to give users the possibility to set these default values explicitly.

19876ced76 Bug #1785: Introduce numext::rint. 
This provides a new op that matches std::rint and previous behavior of
pround. Also adds corresponding unsupported/../Tensor op.
Performance is the same as e. g. floor (tested SSE/AVX).

6fb3e5f176 STYLE: Remove CMake-language block-end command arguments 
Ancient versions of CMake required else(), endif(), and similar block
termination commands to have arguments matching the command starting the block.
This is no longer the preferred style.
